Title: Optical scanner
Inventor: KING HEWSON NICHOLAS GRAHAM
IPC: H04N3/08
Filed: 1967-08-08
Abstract: 1,126,870. Optical scanning arrangement. MULLARD Ltd. 8 Aug., 1967, No. 36358/67. Heading H4F. The Specification describes an optical line scan arrangement, comprising at least three line scan mirrors M1, M2, M3, Fig. 2, reciprocated in orientation with respect to a light source 5, with respective sinusoidal oscillations 1, 2, 3, Fig. 1, regularly staggered in phase from mirror to mirror and means to utilize at 8 reflections by said mirrors singly in turn, for those periods when the respective mirror is undergoing a middle, substantially linear, portion of its sweep in one direction. An approximately linear line scan is thus produced corresponding to the heavy line in Fig. 1. A mirror 7 may undergo a sawtooth reciprocating movement about an axis orthogonal to that of mirrors M1, M2, M3, to produce a frame movement of the line scan 8 and a raster on screen 9. The very rapid sinusoidal movement of the line scan mirror may be produced as shown in Fig. 3, wherein the mirror 10, pivoted at 15, is supported at either end by bi-morph bodies 13, 14 which, under the action of suitably applied potentials, flex in opposite directions and rotate the mirror. A light beam 24, Fig. 5, from the source (e.g. a laser) may be directed to each of the line scan mirrors in turn by means of an optical deflecting arrangement, comprising three calcite birefringent prism assemblies P1, P2, P3 having the property that a light beam 24 having its plane of polarization in a given plane passes straight through the prism interface to emerge at 25, and one with its plane of polarization orthogonal to the first, is reflected by said interface to emerge at 26. Electro-optic switches S1 S2, S3 control the polarization planes of the light beams such that input beam at 24 emerges sequentially at 27, 28, 29, 30, to fall on the four corresponding positioned line scan mirrors 31, 32, 33, 34, Fig. 6 (not shown). The optical deflecting arrangement is dispensed with in the embodiment of Fig., 7, wherein the light beam 45 is moved in a conical scan, to sequentially impinge on the line scan mirrors M1<SP>1</SP>, M2<SP>1</SP>, M3<SP>1</SP>, which are each reciprocated about central axes parallel to 46, by means of respective bi-morph bodies 42, 48, 49. Due to the circular movement of the light spot on the mirrors, the line scan 48 will tend to be curved, and to counteract this, orthogonal reciprocations are imparted to each mirror by means of second bi-morph body pairs 50, Fig. 8 (not shown).

Abstract: 1,199,005. Making filter elements. BENDIX CORP. 8 Aug., 1967 [17 Aug., 1966], No. 36377/67. Heading B1D. A tubular element, for coalescing water from fuel or filtering solids from liquid, is made by rolling a batt 18 of glass fibre spirally, incorporating in the end faces strips 56 of thermoplastic and bonding the roled 'batt to thermoplastac end caps (Fig. 1, not shown) by 'spin welding', in which strips and caps are melted by friction therebetween and then held together. The caps bond to both the strips 56 and the glass fibre. In Fig. 4, strips 56 are folded round the edges of a glass fibre screen 50 which is then rolled to form the outer layer of the roll. Alternatively an extruded strip of U-section (Fig. 6, not shown) or a single strip heat-bonded to screen 50 may be used. If no screen 50 is used (Figs. 1 to 3, not shown), the thermoplastic strips (22) may be laid along the edges of batt 18 before rolling and themselves extend several times round the element. Additional porous supports may be included inside and outside the roll.

Title: Article storing and releasing mechanism
IPC: A47F3/026
Filed: 1965-08-24
Abstract: 1,088,528. Article dispensing apparatus. SEEBURG CORPORATION. Aug. 24, 1965 [Sept. 2, 1964], No. 36387/65. Heading A4T. An article storing and releasing mechanism comprises three vertical chambers 20, 21, 22, Fig. 4, containing columns of cups which may be released one at a time from chamber 21. When all the cups C21 are used a feeler energizes a solenoid 81 which raises a pawl 119 against spring 97, Fig. 6, to lift member 101 via flange 120. A cam 145 on member 101 actuates a latch 135 to open a door 51 (Fig. 11, not shown) between chambers 20, 21, and cam 125 then releases hub 26 so that spring 128 moves the hub and swings a top-hinged flap 71 for shifting the cups C20 from chamber 20 to 21, the shift being sensed to de-energize the solenoid and allow the pawl to move downwards under spring 97 so that it cams on a pin and is snapped by over-centre spring 117 into a vertical position under lip 154. When all cups C20 are dispensed, the solenoid is again energized, so that pawl 119 lifts lip 154 and member 151, Figs. 5, 6, so that lever 155 is raised to release a cup column shifting assembly 60, Fig. 4, which is swung about an upper pin 173 by spring 165 acting via linkage 161, 170 connected to the assembly, so that the lower part of the assembly shifts cups C22 from chamber 22 to 21. A plate 176 on assembly 60 then engages side wall 25 and lifts pin 173 out of notch 175 so that the top of assembly 60 also moves towards chamber 21. To refill the apparatus with cups, the column shifting members must be reset by pushing them back into initial position.

Title: Ignition system for an internal combustion engine
IPC: F02P3/00
Filed: 1969-07-21
Abstract: 1,204,460. Ignition systems. FORD MOTOR CO. Ltd. July 21, 1969 (Aug.1, 1968], No. 36535/69. Heading F1B. An ignition system comprises an inductor 176 connected in series with a source of direct current 26 and adapted to be charged to a predetermined current level for providing a predetermined energy charge to a spark plug 24, means 164 for interrupting current through the inductor, a capacitor 134 connected to the source of direct current, means 150 coupled to the capacitor for limiting the voltage across the capacitor to a predetermined voltage level lower than the voltage of the source, means coupled to the capacitor and the source of electrical energy for causing the capacitor to charge to the predetermined voltage level at the same time as the current through the inductor reaches the predetermined level and means coupled to the inductor, to the capacitor and to the means coupled to the capacitor for limiting voltage across the capacitor for interrupting current through the inductor when the predetermined voltage across the capacitor is reached. When the Zener breakdown voltage of the Zener diode 150 is reached current flows through it in the reverse direction and into the base of the transistor 116 thereby switching transistor 116 to a conducting state. This turns transistor 120 off since the base current into the base 144 is diverted through the collector 140-emmitter 136 of the transistor 116. When the transistor 120 is turned off transistors 152 and 164 are switched to the non-conducting states. When transistor 164 is switched to its non-conducting state current is interrupted through the inductor or primary winding 176 of transformer 178 and the inductively stored electrical energy is transferred to the capacitor 192.

Title: Gain-Adaptive Control.
Inventor: MARTIN ERNEST NORMAN
IPC: G05B13/02
Filed: 1966-08-16
Abstract: 1,190,580. Adaptive control; fluid-pressure servomotor systems. IMPERIAL CHEMICAL INDUSTRIES Ltd. Aug.9, 1967 [Aug.16, 1966], No.36634/66. Headings G3P and G3R. A closed-loop process control system is caused to oscillate with small amplitude at its natural frequency, any deviation in the oscillation amplitude from a desired value being detected and automatically corrected by controlling control system gain. In Fig.1, the pH value of a process, e.g. the neutralization of ammonia liquor with dilute sulphuric acid, is measured at M and compared with a desired value DV by a differential pneumatic device B, any difference being automatically corrected by controlling the setting of a process input valve V. The gain of the system is adjusted to produce small amplitude oscillation at the natural frequency of the system and the controller output signal with a component at this frequency is applied directly and through a restrictor R 1  to a differential pneumatic device 1 which acts as a high-pass filter. Half-wave pulses of the oscillation component are effective through a relay A 1  a non-return valve NR, and a restrictor R 2 , to charge a capacity C 2  having\a constant leakage through a restrictor R 3 . Capacity C 2  thus acquires a pressure corresponding to the mean amplitude deviation of the oscillation component, independent of transients, and this pressure is effective through a booster E and actuator P to adjust the gain of controller B-S so that the oscillation component is maintained at an optimum amplitude despite changes in operating conditions. The output of booster E also limits the pressure applied to relay A so that transient peaks are suppressed. A second oscillation detector may be provided to charge capacity C 2  in dependence on the amplitude of the other half cycles so that operation is full-wave. Capacity C 2  may alternatively be charged in dependence on oscillation detected at the output of measuring device M whenever the deviation is greater at that point. Addition of differential and integral components of control and application to automatic pressure control are referred to. Electrical, mechanical or hydraulic equivalents of the pneumatic units may be utilized.

Title: Improvements in or relating to ultrasonic methods of testing
Inventor: SHARPE ROY SAMUEL
IPC: G01N29/11
Filed: 1960-10-25
Abstract: 930,687. Ultrasonic testing of materials. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 19, 1961 [Oct. 25, 1960], No. 36664/60. Class 40 (7). The grain structure of the outer annular region of a metal (e.g. uranium) bar B (Figs. 1 and 3), or a thick-walled tube, is determined from the trace produced on a fast-response recorder S which records, as a function of time, the amplitude of that part of incident pulses of ultrasonic energy transmitted through this region and reflected from the surface of the smaller arc subtended by the chord connecting the transmitting and receiving transducers T, R (Fig. 1), as the latter traverse the length of the bar which, together with the transducers is mounted in a water bath P and rotated slowly by rollers Q. The transducer T is energized by a generator A supplying pulses of 1 Á/sec. duration and 6 mc/s repetition frequency which also trigger the time base of an oscilloscope C (the trace on which is shown in Fig. 2) and are additionally fed via a variable delay circuit D to control a gate G such that only those pulses corresponding to transmission through the desired region (e.g. pulse 3, Fig. 2, and path 3, Fig. 3) are passed via amplifier H to the recorder 3, transmission on other paths such as 1, 2, &c. being reduced or eliminated by displacing the transducers from the diametral position. If it is also desired to determine the grain structure of the core of the bar a second pair of transducers mounted on a diameter may be utilized. Alternatively, a single pair of larger diameter transducers suitably marked to produce two beams may be employed. The transducers may be piezoelectric crystals and pulse resolution is stated to be improved by fitting rubber marks having rectangular cut-out windows with the longer sides parallel to the bar axis.
